I was always in trouble at school,detention was a permanent thing for me in the first year after that i just didnt bother.
I got in trouble for fighting,swearing at teachers,threatening teachers,not doing course work pretty much everything that you can get in trouble for i did!.
If i got the chance to do it again i would be more well behaved thats for sure.

The occasional detention, nothing major. I had my I.T. account revoked for a fortnight for copying over some softcore porn from a floppy disk though. It was all the craze for a couple of weeks. Unfortunately, I was one of the first and few that were captured. It gave our floppy disks a real hard drive while it lasted though.

I got suspended for grabbing some kid his collar after he made fun of me.

I also made a crack at some girl and she was a bit offended and I apolgized (she accepted) but her fat, overbearing friend with no life and a penchant for drama reported me to the assistant principal and I got detention. She's still a fat waste of space to this day.
